Commenting on my earlies suggestion, Clive Page writes:

. I'd support the suggestion of Morten Krabbe Barfoed that the original

. telescopes: the Wide Field Camera (WFC) [from the UK] and the X-ray
. Telescope (XRT) from Germany, the latter with two detectors (PSPC and
. HRI).  Thus to specify your observation completely you would need
. something like:
. 	TELESCOP='XRT     '
. 	....

Well, perhaps I've expressed myself badly. I simply used an RDF-file
taken from the legacy-server. That file contains among other things 
the following keywords:


The essence of the suggestion is the introduction of a new keyword, 
that contains the same information as the TELESCOP-keyword, without 
altering the usage of the TELESCOP-keyword. The result would be:


- not changing the current description of mission, telescope, detectors
and so on, only adding one keyword, that contains redundant information.
